Fracture mode analysis of cementitious mortars by simultaneous application of 4D-XCT and acoustic emission technique KU Leuven
Cementitious brittle construction materials are susceptible to fracturing due to their heterogeneous material composition and relatively weak bond between the aggregates and paste. Hence, enhanced methods of fracture analysis in these materials are an important subject of research. The acoustic emission technique (AET) is frequently used in the study of brittle construction materials, yet the random nature of cracking and the het erogeneity of ...
Effects of Water Uptake on the Electrical Properties of Carbon Black-Epoxy Nanocomposites KU Leuven
Water ingress in composite structures is a potentially costly problem, and its detection before related damage begins to appear is of utmost importance. Carbon black fillers (CB) and epoxy matrices can be used to produce water-sensitive nanocomposites that can be integrated into composites during production. Nevertheless, the effects of water uptake on the electrical properties of CB-epoxy nanocomposites have scarcely been reported. Therefore, ...
X-Ray-Based 3D Histopathology of the Kidney Using Cryogenic Contrast-Enhanced MicroCT. KU Leuven
The kidney's microstructure, which comprises a highly convoluted tubular and vascular network, can only be partially revealed using classical 2D histology. Considering that the kidney's microstructure is closely related to its function and is often affected by pathologies, there is a need for powerful and high-resolution 3D imaging techniques to visualize the microstructure. Here, we present how cryogenic contrast-enhanced microCT (cryo-CECT) ...
A novel methodology to characterise the ductile-to-brittle transition behaviour of pipeline steels using the dynamic tensile tear test KU Leuven
Brittle fracture control strategies for high-pressure pipelines are essential to prevent catastrophic failures resulting in significant economic losses and environmental damage. Typically, this is achieved by operating the pipeline well above the ductile-to-brittle transition temperature (DBTT). In general, a series of lab-scale fracture tests, such as the Charpy V-Notch (CVN) or Drop Weight Tear Test (DWTT), are performed at different ...
Numerical and experimental optimization of blind rivet nuts for novel applications KU Leuven
The interest in optimized lightweight and durable structures for automotive and aerospace applications has become more prominent than ever. This is driven by the pressing need to save energy and reduce emissions. The latter often results in the concept of multi-material design, sparked by new emerging materials, challenging well established mechanical joining techniques. A Blind Rivet Nut (BRN) joint is an example of such a mechanical joining ...
